Struct timely::container::flatcontainer::impls::codec::MisraGries

pub struct MisraGries<T> { /* private fields */ }

Maintains a summary of “heavy hitters” in a presented collection of items.

Implementations

impl<T> MisraGries<T>

where T: Ord,

pub fn insert(&mut self, element: T)

Inserts an additional element to the summary.

pub fn update(&mut self, element: T, count: usize)

Inserts multiple copies of an element to the summary.

pub fn with_capacity(k: usize) -> MisraGries<T>

Allocates a Misra-Gries summary which intends to hold up to k examples.

After n insertions it will contain only elements that were inserted at least n/k times. The actual memory use is proportional to 2 * k, so that we can amortize the consolidation.

pub fn done(self) -> Vec<(T, usize)>

Completes the summary, and extracts the items and their counts.

Trait Implementations

impl<T> Clone for MisraGries<T>

where T: Clone,

fn clone(&self) -> MisraGries<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for MisraGries<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Default for MisraGries<T>

fn default() -> MisraGries<T>

Returns the “default value” for a type.
